Document the new workflow where users can browse Flickr search results
directly in the interface instead of visiting Flickr's search page.

Instead of showing a link to search Flickr, the app now performs the
search directly and displays results as a grid of thumbnails. Each photo
shows the photographer's name and license (with Wikipedia-compatible
licenses highlighted in green). Clicking a photo takes the user to the
message composition page with the selected image displayed alongside.
Includes validation to ensure image URLs are from Flickr's static servers.
